1 .avrnwnrrrne MACHINE.

. Application filed August 25, 1923, Serial No. 659,273. Renewed October 10, 1924.

This invention relates to manifolding typewriting machines of the continuous billing type, in which a composite sheet or web is fed around the cylindrical platen, the web comprising several plies of worksheets having successive corresponding forms printed thereon, said plies beingls ometimes separated from each other. and sometimes joined at their side edges to form a fanfolded web, the various plies havin carbonsheets interleaved therebetween W ich are displaceable at intervals along the web to fresh sets of forms. The invention relates more particularly to means to facilitate'the relative displacing or shifting between the carbon-sheets and the work-sheets.

One form of this kind of machine is dis closed in the patent to Wernery & Smith, No. 1,132,055, datedMarch 16, 1915. In said machine the platen is mounted in a swing frame by which it may be displaced upwardly, from its normal typing position,

so as to enable that portion of the web co'ntaining the carbon-sheets to be straightened out preparatory to a carbon-displaclng operation.

Another form of machine for handling this kind of work is'disclosed in the applica-' tion ofB. C. Stickney, Serial No. 647,501, filed June 25, 1923 (now Patent No. 1,582, 438, of April 27, 1926), in which there is provided means to so condition the web that there may be a relative shiftingbe tween the work-sheets and the carbon-sheets without lifting the platen, the platen remaining always in its usual typing position, To this end there is provided in said .machine a normally-ineffective curved table, which may be moved to effective position to so condition the web that it is disposed in a curve ofcomparatively large. radius, after which a pivoted carbon-carrier, to which the ends'of the carbon-sheets are attached, may be actuated to draw the carbon-sheets rearwardlyto displace them relatively to the work-sheets while the latter are being held, the leading edges of the work-sheets remaining around the platen, so that they may be readilyffed with the carbon-sheets around' the platen after a carbon-displacing operation.

Still another form ofmachine of this generalclass is disclosed inmy co-pending applicationSerial'No. 645,995, filed June 18, 1923 (now Patent No. 1,578,941, of March in the provision of stopping means to hmit 30, 1926), in which there is provided a curved table which is relatively fixed, over which the web is conducted to the platen, a carbon-carrier being arranged behind said table and slidable on a rearward extension of said table, so that it may travel with the web towards the platen and may be .pushed rearwardly on said table to withdraw the web around the platen to condition the web for a relative shifting between the carbonafter which the work-sheets may be fed forwardly, while the carbon-sheets are held, to shift said work-sheets relatively to the carbon-sheets, a gage being provided at the deliveryside of the platen to determine the extent of shifting of said Work-sheets.

Another feature of the invention is the provision of means whereby slack is created in' that portion of the web between the platen and the carbon-carrier, to avoid hindrance of the feeding of the web around the platen, which sometimes results in slipping between the platen and the worksheets during rapid line-spacing operations. This slack is created in the web bythe carbon=carrier when it returns to its normal position.

A feature of the invention is the provision of means comprising a guide-plate to prevent the slack, created in the web, from piling up on the platen. a

A further feature of the invention resides the reclprocatory movements, of the carboncarrier,.said means comprisin an actuating 7 arm provided with -.a pin, which plays back and forth in a slot of an arm connected with the carbon-carrier, said pinengaging-in the 110 65. sheets andthe work-sheets by freeing the with the work-sheets around the platen to free the carbon-sheets from said platen,

end of the slot in both the normal position and the operated position of the carbon-carrier to arrest said carbon-carrier in said positions.

Other features and advantages will here inafter appear.

In the accompanying drawings,

Fi ure 1 is a part-sectional side view of an nderwood typewritin machine, showing the invention applied t iereto, and showing the parts in their normal typing posltion, and a set of forms nearing the completion of typing.

Figure 2 is a view similar to Figure 1, but shows the carbon-carrier swung to its effective position to withdraw the web around the platen to free the carbon-sheets -while the carbon-sheets are held free from said platen after the feed-rollers have been released.

Figure 3 is a top plan view of the machine, with the-parts shown in the posit-ion indicated in Flgure 2.

Figure 4 is a view similar to Figure 2, some of the parts being omitted, and shows thefeed-rollers thrown on and the worksheets advanced around the platen to a age om the platen by the carbon-carrier.

Figure 5 is a diagrammatic side View,

showing the carbon-carrier raised to its normal position to thus create slack in the web behind the platen, and showing also the web fed to the second gage to bring the bottoms of the typed set of forms to the knife, where they may be severed, and the leading ends of the carbon-sheets to' the printing point,

to proceed with the typing of a fresh set offorms.

.' Type-bars 1'0 strike against the front of a revoluble' platen 11, which is journaled,

.in the usual manner in, a platen-frame comrising ends .12 and a rear paper-shelf 13.

he usual front and rear feed-rolls 14 run on the under side of the platen. They may be released, or thrown from the platen, by means of a finger-piece 15, connected by a link 16 to an arm 17, fast on a shaft 18. The shaft 18 is provided with flats against which arms 19, forming part of levers 20, are held b spring-pressure. The levers 20 are pivote on a shaft 21, so that when the finger-piece 15 is actuated, and the arms 19- spread apart by turning of the shaft 18, the levers 20, which support the pressurerolls, are rocked on the shaft 21 to release the rolls. This roll-releasing structure is that commonly found in the standard Underwood Etypewritin machine.

- The work-web, usua y comprising superposed plies 22 (which may be separate or which'may form-a fan-fold), is drawn up from a supply-spool, or from a zigzag folded pile (not shown), but which may be contained in a receptacle arranged in the rear of the typewriting machine and its stand; In the normal or typing position of the parts, the work-webs on rising from their poses hereinafter mentioned, are obviously supported at 28. around the rod 26, and are thus directed downward through a carbon-carrier 29 where-they are interleaved with carbons 30. Each of the carbons 30 has its rear end at tached to one of two blades 31, carried by standards 32 on the ends of aplate 33. The plate 33 is secured to a bar 34,. supported at its'ends by ears 35, offsetone from each of the pivotall -1nounted arms 27.

The work-plies are turned- From the car on-carrier thecomposite web drops in the form of a slack 36 (that is to say when the parts are in, the Figure 1 or typing position) again onto the surface of the table 25, and is thus led forward on the surface of the table 25 over the front edge 37 thereof, sli htly above and forward of the rear upper e go of the paper-shelf 13.- it will be noted that the table 25 is of long arcuate curvature, rising-at its center portion well above the upper edge of the papershelf and turning down at its forward end so as to direct the web tangentially therefrom, over the paper-shelf 13 to the rear under face of the platen. The web is thus guided around the platen up across the printing line, and along and in front of a staff 38, to which is adjustablysecured, by means of a thumb-screw 39, agage 40, the purpose of which gage will hereinafter more fully appear.

( The table 25 is astat-ionary table. It is supported at either side, at the front part thereof, by a pair of arms 41 turned upward from brackets 42, which latter are extended horizontally forward from the arms 41, and at their forward ends are secured to the under face of the usual cross tie or bar 43 which connects the side pieces. of a carriage 44. In its rear part, the table 25 is supported by a air of arms 45, which are con-- nected to an supported by downwardly-inclined extensions 46 of the brackets 42. At the ends of the inclines -46 ofthe brackets 42, these brackets are again offset horizon- Y tally at 47, rearward,-and'at their rear ends are again offset downward at 48. The downward" offset or rear 48 of each of the brackets 42 is secured to a bar 49, which extends crosswise of the machine and serves to connect these brackets and to form with the brackets a frame. Dependingfrom the bar 49 area pair of brackets 50, on which are 'ournaled rollers 51 which ride on a rail 52;

e rail 52 is supported by a pair of brackets 53, one at each side of the machine, and each of the brackets 53 being secured,a's at in the form of a curved plate 57, is provided.

54 to the. main frame v5 5 of the machine.

The platen-carriage 44 is mounted on a rail.

56 for movement in letter feed and return. directions on the main frame 55 of the machine. It, therefore, follows that. the frame, which isiformed by the brackets 42 and the rear cross-bar 49, is in the nature of a subcarriage attached to the platen-carriage and supported on front and rear rails 56 and 52, respectively, for movement in letter feed and return directions with the,platen-carriage; and that the table 25, over which the web is fed to the platen-carriage, is a table which travels with the'latter, by virtue of its connections and supports 41 and 45 on the bracketsarms 42 and 46, respectively.

in order that the slack36 in the web between the carbon-carrier and the platen may not collapse or slide forward off the table and down onto the platen, a guard,

This plate 57 has ears 58 turned from the edges thereof, and thcse'are offset under the side edges of the table 25 where they are secured at 59'to the table; the guard 57 being thus supported and carried by the table 25 in the movements of the latter. The guard 57 is curved tangentially to the table at the front of the latter; a space being provided between the guard and the table at 60 just sufficient to permit passage of the web between the work. The guard-plate may press lightly against the web to retain the latter; that is to say, prevent the web from slipping forward between the work. Guards .61 on the paper-shelf 13 are also provided for the side edges of the table.

I These guards are in thetformof ears struck ,up from flat plates which have their;

upper ends curled at 63 to be sprung over and retained by the curved edge 64: of the paper-shelf 1S. Theguards 61 are thus adjustable over the paper-shelf 13 to accommodate difierent widths of web.

Assuming that typing on the leading form-section of the Web has been completed, the first step in conditioning the web, preliminary to a relative shift of the carbons and work-plies, to withdraw the carbons from the typed leading form-section to set the same in the next untyped form-section, is to eliminate any slack 36 remaining in the web and to flatten the web out'on-the curved surface of the table 25, so that therelative movement of the carbons and workspliesmay be a smooth and eas movement made without possibility of fou ing of the sheets.

The movement of the carbon-carrier from Figure 1 to Figure 2 position is, however, a further important object, to Wlt, the retraction of the web around the platen so as to clear the carbon-sheets from the platen. In the use of the apparatus shown in the drawings, actual shift of the work-plies relative .to the carbons is effected by foren after the parts have been moved to the Figure 2 position. If this operation -is to take place, it is obvious that'the carbons must be clear of the platen, so that they will not move forward, sot-hat they may be held ward feed of the'work-plies around the platagainst forward movement when the platen arts to feed the work-plies forward. As a preliminary to the movement of the carboni-arrier to the Figure 2 position, the feedrolls let. are released, so that the refraction of the web by thecarlmn-carrier may be effol-ted, so that there may be no drag on the carrier arms 27, as hereinbefore stated, are

pivoted at 28. The-pivot is provided by a rock shaftoti, which has its hearings in ears 67 turned down from the lower horizontal portions 47 of the brackets'42, one at each side of the carriage. Working in a slot 68 of the arm 65 is apin 69on the end of one arm 70 of a bell-crank journaled at 71 on anear 72 turned forward from the downwardly-inclined portion 46 of the'left-hand bracket 42. The other arm 73'of this bellc-rank isronnected at 74 to a link 75, the other end of which link connects at 76 to a rear arm .7 7 of another bell-crank journaled at 78 on the left-hand bracket-arm 4C1. The

other arm of this latterbell-crank is a forwardly-extending arm 79, which terminates in a handle 80, by means of which thecarboncarrier is operated. It follows that when the handle 80 is drawn forward and downward-from.Figure 1 to Figure 2 position, the link 7 5 is lifted, the arm 70 rocked upward and rearward'to cause the pin 69 to rock the carbon-carrier supporting arms 27 downward and rearward. The pin-and-slot connection 6 869 between'the arms 65 and 70 provides the necessary play between the levers thus connected. The end wall of the slot 68, as shown in Figures land 2, by engagement of the in 69 therewith, determines the Figure 1 ans Figure 2 positions of the carbon-carrier, and. consequently determines the throw of the carbon-carrierand of the operating lever 79.

The parts being in Figure 2 position, the pressure-rolls 14 are then re-applied preliminary to feed of the work plies forward.

-This feed may be efiected'by turning the platen by means of one of the finger-knobs 81 or by the line-space wheel 82, ordinarily found upon and made fast to the axle of the platen. During this forward rotation of t-hepla'ten,.the handle 80 may be held by a the operator to hold the carbon-carrier in Figure 2 position against movement Wltll the work-plies. The lower end 83 (see Figure 4) of the arm 84, unitary with the gage 40, serves to determine, by registration therewith of the leading ends of the work-plies, the amount of advance of the work-plies required properly to position the carbons with the next untyped form-sections of the workplies, and to clear the carbons of the leading typed form-sections after detachment of the latter. 7

' It remains then to advance the compbsite web to position wherein .suchdetachment of the leading type form-sections may be effected, and to position the web'at commencement of typing at the next untyped formsectionsthereof. It is for this purpose that the gage 40- is provided, as shown in Figure 5. The movement of the composite web to bring the leading ends of the work-plies to the gage 40 is effected by a further forward rotary movement of the platen. Preliminary to such further forward rotary movement of theplaten, and in order that the carbons may be advanced with the work plies during such movement, the handle 80 ting edge of a blade 85, so that the typed form-section may be severed from the rest of theweb by drawing the web against the blade. The blade 85, asshown in Figure 3,

is secured at its ends to brackets 86, in turn, secured to the end pieces12 of the platenframe. The brackets 86 also serve to support a cross or table plate 87, to which the gage-stall 38 is centrally secured at 88.

' After detachment .ofthe typed form-section, "or without detaching such formrsec tion, typing on the next form may be commenced.

Variations may be resorted to within. the scope of the invention, and portions of the improvements may be used without others. 1Having thus described my invention, I c aim i" 1. In a continuous billing t'ypewriting g machine, thecombination of a-carriage, a
